Question 24 of 510
Quick Answer
The answer is the `panic=10` kernel parameter, which you add to the GRUB command line to capture a kernel panic message in Linux. This works because the `panic=<seconds>` parameter tells the kernel to pause for that many seconds after a panic occurs before rebooting or halting; setting it to 10 gives you a clear window to read and record the critical error output on the console. On the CompTIA Linux+ XK0-005 exam, this tests your ability to troubleshoot boot failures by modifying kernel boot parameters—a common trap is confusing `panic=` with `crashkernel=` or forgetting that the value must be added to the `linux` line in GRUB. The key distinction is that `panic=` controls the post-panic delay, not the memory dump. Memory tip: think “Pause for Panic”—the number after `panic=` is the seconds you buy to see the message before the system disappears.
XK0-005 Troubleshooting Practice Question
This XK0-005 practice question tests your understanding of troubleshooting. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A Linux server experiences a kernel panic during boot. You need to capture the panic message for analysis. Which kernel parameter should be added to the GRUB command line to ensure the panic message is displayed before the system halts?

Correct answer & explanation
✓
panic=10
The `panic=<seconds>` kernel parameter instructs the kernel to wait the specified number of seconds after a kernel panic before automatically rebooting. By setting `panic=10`, the system pauses for 10 seconds, allowing the panic message to remain on the console for capture and analysis before the system halts or reboots. This is the correct parameter to ensure the panic output is visible.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse `panic=` with a boot-time delay or a recovery mode option, mistakenly thinking `single` or `quiet` will help display the panic message, when in fact `panic=` is the specific parameter that controls the post-panic behavior to keep the message visible.
Detailed technical explanation
How to think about this question
The `panic` parameter is part of the kernel's `printk` and panic handling subsystem; when a panic occurs, the kernel calls `panic()` which prints the panic message and then either halts or reboots based on the `panic_timeout` variable set by this parameter. In real-world scenarios, setting `panic=0` (default) causes an indefinite hang, while a positive value triggers an automatic reboot after the delay, which is useful for headless servers where a crash must be captured via serial console logs or remote management tools.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the XK0-005 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
